Sounds like Synergy got there not a moment too soon! Good luck in sorting things out, we'll still be here looking forward to business as normal. :-)

Or bruno, knowing synergy was on the way, held out as long as he could before crashing. Either way, bruno has been a good soldier, hope you can get him back in business again.

Keep up the excellent work, Matt and let's try to revive Bruno before his untimely demise ??? All in fun though, I was just wondering why my uploads were just sitting here and now I know, and can stop worrying ...

I would disagree with the statement that we can make do without redundant servers for this project. Considering the number of hosts are now over 2 million for just this project that is an incredible amount of computing power and really was the spirit of the architectural design. The work still needs to go somewhere.

I don't think some people here realize the scope of the data returned and the impact of the loss of storage devices. To serve the project as has been demanded by the users, some are very vocal, there does need to be many factors considered.

It isn't about throwing money at a problem in hopes of a resolution. Things break and need to be replaced over time - requiring money or donations to achieve the goal. Not much different that expecting to drive your new car with the same tires for 150k miles or not getting an oil change.

When your dataset increases, your load and time between failures also increases. When trying to make do with piecemeal equipment it can be very challenging to make a go of it.

Bruno hardware failure - this suggests bruno (the upload server) is a single point of failure, is it feasible to have two systems performing the same function here?

Perhaps bruno should have a companion, borat (I'm probably thinking of the wrong bruno here.)

BOINC is supposed to make it possible to do big science on a vanishingly small budget. That means redundant servers are often out of the question.

So instead of redundant servers so that something can always take work, we have a client that handles outages gracefully.

It has to be that way because the standard solution (throw money at the problem) is not available to BOINC projects.

They do have some redundancy. The DB is mirrored in real time. They have raid for their drive arrays. But having completely redundant servers is too expensive.

It's been my experience that when the dataset increases, MTBF (Mean Time Between Failures) decreases... and your load increases by a factor of two or more (for a dataset double, your load quadruples... not saying that the increase is always exponential, though...)
